FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What type of terminal block is the Wago 280-104?
The Wago 280-104 is a 2-conductor through terminal block with a rated cross-section of 2.5 mm², suitable for Ex i (intrinsically safe) applications.
What are the rated currents for aluminum conductors?
Due to the lower conductivity of aluminum, the rated currents are reduced: 2.5 mm² aluminum conductor → 16 A, 4 mm² aluminum conductor → 22 A
What is the maximum aluminum conductor size supported by the Wago 280-104?
When using “Alu-Plus” Contact Paste, it supports aluminum conductors up to 4 mm² (12 AWG).
